Publishing result in Silkperformer

SilkPerformer reports percentiles in a different section than the main table and it can be time consuming, if you want to publish all the metrics in a single table. Therefore to solve this issue, a colleague (Murray Wardle) of mine wrote a visual basic script that generates a table with all the metrics.

He has kindly allowed me to share it here and below is his description on how to use it.

"Publishing results from SilkPerformer can sometimes be very time consuming. Most projects will have requirements involving the 90th or 95th percentiles and for some reason SilkPerformer reports percentiles in a different section of the report and not in the main table I wish to publish.

Generally in my scripts I’ll use Timers for measuring response times (I’m not too keen of the automatic page and form timers) for timers controlled with the MeasureStart() and MeasureStop() functions, Inserting the following into the TInit will enable percentiles to be calculated for the Timers.

MeasureCalculatePercentiles(NULL,MEASURE_TIMER_RESPONSETIME);

Unfortunately percentiles are displayed in a different section of the report to the Min, Avg, Max, StdDev, Count, and it’s a waste of time trying to copy and paste the values into a spreadsheet.

So, here is a simple little script which does the work. Just drag and drop the OverviewReport.xml file onto the script and it will create a csv file with the following:

ScriptName, TimerName, Min, Avg, Max, StDev, Count, 50th Perc, 90th Perc, 95th Perc, 99th Perc"

Example:
1: Save the above code as a visual basic script into a folder. Lets call this script as "ExtractOverviewReportData.vbs".
2: Navigate to you SilkPerformer project and copy OverviewReport.xml into the folder where you have saved vbs script. See the screenshot below.

When you open the xml file, it would look something like this:

3:Now drag and drop the OverviewReport.xml file onto the script and it will create a csv file.

4: Now open up the csv file in excel and you should have all the necessary metric. You will see something like this:
